Cylindrical Lithium-Ion Battery Cells

Cylindrical Lithium-Ion (Li-Ion) battery cells. Used for small power tools, notebook computers, digital cameras.

• Rated Voltage: 3.7V (85% energy is discharged above 3.6V)
• Precisions in dimensions and weight
• diameter: -0.2mm ~ 0mm
• Length: -0.3mm ~ 0mm
• Weight: -1g ~ +1g
• Operating temperatures:
• Charging temp.: 0 ~ 45°C
• Discharge temp.: -20 ~ 60°C
• Storage temp.: -20 ~ 45°C
• Recomended charge method:
• If voltage is below 1.5V, don't charge, i.e. dispense the battery.
• If voltage is between 1.5V and 3.0V, charge slowly, e.g. 0.01C.
• If voltage is between 3.0V and 4.2V, charge at 0.5C (standard is 0.2C; max is 1C) until 4.2V.
• Charge with 4.2V (+/- 0.05V) until current < 0.05C.
• Recomended discharge method:
• Discharge current depends on application. The average current should be under 1C. The instantaneous current should be under 2C. Stop discharge when voltage is below 3.0V. Discharge under 0.5C can have longer cycle life.
• Cycles Life
• After charging/discharging at 0.2C for 500 cycles, the retained capacity is 80%~85%. The higher the full charge voltage, the shorter the cycle life. Their relations are:
  
• 4.25V: 300 cycles
  
• 4.20V: 500 cycles
  
• 4.10V: 800 cycles

• Custom design for special dimensions welcome.
• Sample order accepted.
• FAQ:
• Q: What's 0.5CmA?
• A: If capacity is 600mAh, 0.5CmA = 0.5 x 600 mA = 300mA.
• Q: What do S, R, P mean in the model number?
• A: S: Stainless Steel, A: Aluminum, P: Polymer
• ROHS
• Lithium-ion cell is environmental friendly. All cells comply with ROHS standard.

• UL
